The flexor digiti minimi brevis ( Latin for “short little finger flexor”) is a skeletal muscle and one of the muscles of the little finger ball ( hypothenar ) of the metacarpal . It arises from the flexor retinaculum and hookbone and attaches to the inside of the base of the first phalanx of the little finger. The flexor digiti minimi brevis muscle flexes the first phalanx of the little finger (flexion in the metacarpophalangeal joint ).
